This, cooling fluid can pass through the second valve head 106 and spray S1 to emit the first taper (cone), but cooling fluid cannot be
It is transmitted between first valve head 128 and nozzle body 102.It can be said that in the first opening stage, the cooling stream in nozzle body 112
The pressure of body is less than the threshold pressure set by the power F generated by biasing apparatus 108, and the first valve head 128 is maintained at and is closed
Close position.This arrangement is in the case where cooling fluid is supplied with low pressure and/or low flow velocity may be for example useful.
Increase with the pressure of the cooling fluid in nozzle body 112, injection nozzle 100 can be in the second opening stage
Operation.In the second opening stage, the cooling fluid in nozzle body 112 can be pressurized to second pressure, the second pressure
It is at least big as the threshold pressure set by biasing apparatus 108.It is same as above, cooling fluid by by-pass line 150 most
The flow cavity 117 being supplied to eventually in nozzle body 102.Some fluids in the fluid are discharged from the second valve head 106 naturally
To emit the first conical jet S1.Remainder bears against the back side of the exposure of the seating surface 132 of outer valve stem 104.Once stream
Pressure in dynamic cavity 117 reaches threshold pressure, just pushes valve rod 104 to nozzle body 102 so that the first valve head 128
Seating surface 132 moves away valve seat 120 to open the first valve head 128.It, should when desired high pressure and the cooling fluid of high flow rate
Therefore second opening stage is advantageous.
As shown in Fig. 2, when valve rod 104 occupies closed position, it is couple to the biasing apparatus 108 of the proximal end 124 of valve rod 104
Nut 144 and 102 d spaced apart of nozzle body.But when pressure is established in nozzle body 112 and 104 court of valve rod
When being moved to nozzle body 102, nut 144 is contacted with the proximal end 116 of jet stem 102.In this way, nozzle body 102 is used as in valve
The retainer of the movement of limitation valve rod 104 when bar 104 reaches maximum open position.In any open position, from the first valve head 128
Seating surface 132 and the valve seat 120 of nozzle body 102 between clearance G emit the second conical jet S2.It should be understood that
It is that in fig. 2, the first valve head 128 is depicted in closed position, but the second conical jet S2 and clearance G are identified as only to use
In explanation.From the foregoing description it should be understood that since the second valve head 106 is fixed on the fluid in the first valve head 128
The fact inside outlet 119, when valve rod 104 is moved to maximum open position from closed position, the second valve head 106 is also with valve
Bar 104 moves.However, this movement of the second valve head 106 is without respect to the first valve head 128 or valve rod 104, and to its property
It can not influence.
As described above, in order to make the cooling fluid supplied in nozzle body 112 reach the second valve head 106, must transmit
Pass through the by-pass line 150 in nozzle body 102, the flow cavity 117 in nozzle body 102, the fluid conduit systems in valve rod 104
134a, 134b and be finally fluid outlet 119.However, the modification of the design is intended to scope of the present disclosure interior.
Fig. 3 depicts the injection nozzle 100 of the replacement constructed according to the principle of present disclosure.In figure 3, in addition to spray
The flow path of cooling fluid between mouth shell 112 and the second valve head 106, the injection nozzle 100 substantially with the spray in Fig. 2
It is identical to penetrate nozzle 100.Specifically, in figure 3, valve rod 104 is included between nozzle body 112 and the second valve head 106 and realizes directly
Connect the single fluid conduit systems 134 of fluid communication.Fluid conduit systems 134 in Fig. 3 are along longitudinal axis A in the proximal end of valve rod 104 124
Extend between distal end 126, and be directly connected to fluid outlet 119, fluid outlet 119 is directly connected to the second valve head 106 again.
Another difference is that the injection nozzle in Fig. 3 is not shown including the locking pin 157 by nut 144 and valve rod 104.But at some
In form, locking pin 157 can also include in figure 3.When including locking pin 157, it may be desirable to by locking pin 157 from valve rod
104 off-centring, such as the flowing of the fluid by fluid conduit systems 134 is not interfered.Injection nozzle 100 in Fig. 3 it is all
Other structures and functional character are identical as the injection nozzle 100 in Fig. 2, and this will not be repeated again.One of arrangement in Fig. 3
Advantage can be the second valve head 106 nozzle 135 by way of the single fluid conduit systems 134 across valve rod 140 come with nozzle
The fluid in direct fluid communication pressurizeed in shell 112, this may insure that cooling fluid reaches the second valve head 106, and not suffering from can
The interruption that can be happened in the flow cavity 117 with reference to 2 the disclosed embodiments of figure or fluid flowing are upset.
Based on foregoing teachings, this disclosure provides a kind of injection nozzle, can be under low pressure and low flow velocity
It operates in one opening stage, and is operated in the second stage under high pressure and high flow rate, this phase advantageously in similar application
Total pressure and flow rates are increased than known injection nozzle.In addition, this disclosure provides a kind of with optimization
The very simple and compact design of service life.That is, since biasing apparatus is only located in cooling fluid flow path,
So it is not exposed in the temperature for residing in the overheat in steam pipe, the temperature of the overheat can reduce and weaken biasing apparatus portion
Part.In addition, in some embodiments, biasing apparatus has very simple construction, only include the spiral shell for the proximal end for being attached to valve rod
Female and spring.Axially and radially size is minimized the entirety of the component permission injection nozzle of this minimum number, this contributes to
Processing reduces material cost, and reduces the overall dimension of steam pipe or other Steam conditioning devices that nozzle is attached to.
